In January-February 1971 five replicate 0.07 m² Van Veen grabs
were obtained from each of 12 stations in Arthur Harbor and nine Van
Veen grabs were obtained from two stations in nearby Bismark Strait.
The 69 grab samples yielded 78,395 individuals which were separated
into 282 taxa, including 108 species...
A procedural manual for sampling and analyzing sanitary landfill
leachate was designed to guide sanitarians and other public health
officials in monitoring mineral and organic material drainage from
landfill sources. The manual was constructed to allow flexibility of
conducting analytical tests in a field or laboratory environment.
Step-by-step procedures for...
This study describes the development and analysis of a manual
for management and supervisory personnel involved with employee
training programs in sanitary food production in the frozen fruit and
vegetable industry. The physical aspects of the plant, microbiology
of frozen foods, and employee training are discussed in relationship
to the...
The effects of bicycle exercise on specific anthropometric and
physiological measures were observed in two test subjects (S1 and S2)
over a twelve week exercise period. The two subjects, one male (S1)
and one female (S2) participated in a graduated bicycle exercise program.
Body weight, body measurements, circulatory function tests,...
This thesis reports on an investigation of the growth, by
Molecular Beam Epitaxy, of III,III-V ternary compound semiconductors.
Strained and unstrained growth was studied via the deposition of InGaAs
on GaAs and InP substrates. Lattice matched InGaAs on InP was grown,
and an in situ method was developed to find...
This thesis reports on the crystal growth, fabrication,
modeling and performance of Graded Index-Separate Confinement
Heterostructure laser diodes which contain pseudomorphic InGaAs as the
active region material. Laser epitaxial layers were grown with
different indium mole-fractions, and a constant InGaAs layer thickness
of 10 nm, on both sides of the...
GaAs MESFETs are widely used in high speed integrated circuits (ICs) and
microwave circuits. Due to the materials and processing methods used in GaAs
MESFET fabrication, deep level traps in the substrate materials have a strong influence
on device performance.
In this work we used the drain current transient characterization...
